Support IP_TOS and IPV6_TCLASS socket options for hostinet sockets.
There are two potential ways of sending a TOS byte with outgoing packets:
including a control message in sendmsg, or setting the IP_TOS/IPV6_TCLASS
socket options (for IPV4 and IPV6 respectively). This change lets hostinet
support the latter.
Fixes #1188
